Application mea January 9, 19215. serial No.' 1,342.

To all whom t may concern:

Be it'known that I, HENRY P. HEEREN, a citizen of the United States, andva resident ofLake Township, in thecounty ofVVood and the State of Ohio,have invented a new and. useful Internal-Combustion Engine, which'invention isfully set forth in the following specification. y Y

My invention has for its object to provide a valve mechanism forinternal combustion engines whereby large port openings, that is, portopenings having large cross sectional areas may be quickly opened andclosed at'the proper times in the cycle of operations-of the engine, andwhich are operated by the ordinary cam shaft of the engine. The valvesare so constructed Vthat the passage ways to and from the engine formingthe intake, vand exhaust passage the following description and uponexamiso that by slight rotation of the valves 9 Ways are operated totheir full extent by a very short movement of the valves and yet produceyopenings of a large crossv sectional area for the admission. of vaporson the one hand andthe exit of ,exhaustgases on the other. The inventionalso provides features and advantages that will `appear. in

nation of the drawings.

The invention ma be contained in internal combustion engines ofdifferent forms'.

Toillustrate a practical application of the.

invention and topresent a description thereof in detail, I have selectedan engine containing the invention` as an example of thedifferentembodiments of my invention, and shall describe it hereinafter.The engine selected-as an example is shown in the vaccompanyingdrawings.V Y

Flgure 1 of the drawings illustrates a top view of the engine, a partbeing shown broken away. This part shows the valve members in section.Fig. 2 illustrates a side and broken view of the engine. Fig. 3illustrates a view of a section taken'on the line 3 3 indicated in Fig.2. y V

The engine 1 has a head 2 that may be located onthe cylinder block 3 ofany of the well known types of internal combustion` engines. Thecylinder block 3 is provided with the cylinders 1, in which are'locatedthe pistons 5. The head 2 vprovided with spark plugsv 6 thatrignitetheyfuel that is drawn into the cylinders and compressed by the pistons inthe manner well known in the art. Thefhead2 is'provided withk a waterchamber 7 'that communicates with the chamber 8 located in the cylinderblock 3.`

The chambers 7 and 8 form the usual watery jacket for maintaining theengine as cool asV may be. v

The valves for controlling the intakeA and outfiow of the gases arelocated in the head 2. The valves 9 and 10 are cylindrical in form andare located in shells 11 that are formed integral with the head 2 atpoints above the cylinders 4. They control the flow of the gases throughthe ports'12 and V13. The interior of the valves 9 communicate with theexhaust manifold 14 for carrying away .the products of combustion whilethe valves 10 are connected` to the intake manifold 15 and control theflow of the fuel mixt'ure into the ignition chambers 16 located in thehead 2 of the engine. The ports 12 and 13 are in the form Vof long slotshaving, comparatively speaking, a narrow width and thevalves 9 and 10are provided with the ports 18 havlng a length and width substantiallythe same as the length and width of the ports 12 Vand 13, and so thatwhen the ports 18 register with the ports 12 and 13 the passage way fromthe manifolds to the combustion chambers of the engine will be opened,and

and 10 the passage ways will be closed. The

Vand are so kformed as toabut t-he wall of the head. The exhaust valves9 yare pressed against the -side wall of the head with considerablepressure, owing to the pressure produced at the time that the valve risopened during the escape of the burnt gases. The wall ofthe head isprovided with anvils 19 that are located centrally with respect to theaxis of rotation of the valves 9 and 10. The anvils 19 'are' bosses thatare formed integral with the side wall of the head. The openings of themanifolds register with the openingsof the cylindrical chambers 9 and 10and preferably have `diameters at these points larger than the interiordiameters of the cylindrical valves.

The side wall 2O of the head made-rehead by means ofthe bolts 2l. Thewall 2O forms a `cover for covering one side ofthe head. It forms achamber in which thel part of the mechanism-forloperatingthe valves islanvils 19. The projectionshave recesses that communicate with channels24C that extend alongthe upper sides oit the valves. The recesses 23 arelocated belowa pipe 25 having openingsthat are located above therecesses 23. The pipe 25 connects with an oil pump andthe voil is fedfrom theV well of they crank 'shaft casing into the pipe 25, in themanner well known in the art and then dripsthiough the openings 26 intothe recesses 23. Vlt flows along the channels 2e and thus lubricates theentire surface o'l the valves9 and l0.

` The valves 9 and 10 are operated by means of the push rods 27 that/areactuated by the cams 28. of the cain 'shalt 29. The projections 22 areprovided with recesses 30 in which the upper ends oi the rods 27 aremaintained by means of the springs 3i that operate to tilt theprojecting parts 22 ot' the i valves 'against the ends Jor the rods 27,the rods being l'ocat'edlon thezopposite sides of the -aires ofthevalves 'from that on which the springs are located. ,As the valves aretilted backand torthlthe oil that 'drips lroni the pipe 25 Works'backinbetween'the surfaces of the valves and their rshells ll. The springs"31 are secured 'in position by' means of the 'knobs 32 that areAlocated'on the proj ectinggparts 22 of the' valves, land the knobs 33that are located on plates 34. The yplates 34 rest upon thecylinder'block `3 oit' the engine and aremaintained in their positionsby the rods 27 that extend through the plates 34.

Thus by my inventionl have provided an exceedingly simple constructionwhereby the parts may be'ieadily assembled'fto forni the engine head orf the engine head may be readily taken' apart rfor purposes ofexamination and of repair.
